Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold design support device for supporting mold design, and in particular, it is constructed by laminating a plurality of plates and molds such as mold dies and press progressive dies. The present invention relates to a die design support device that supports component attachment to a die and machining of component attachment holes.

[0002]

2. Description of the Related Art FIG. 15 is a block diagram showing the overall structure of a conventional die design support apparatus. The hardware configuration mainly includes the CPU 1, the external storage device 2, the main storage device 3,
It comprises a display device 6, an input device 7 and an output device 8. The external storage device 2 stores a parts database (a "database" is also referred to as "D / B" in the drawing) 2a, a composite hole database 2b, a simple hole figure database 2c, and a simple hole machining database. The main storage device 3 also stores a software unit 4 and an edited drawing database 5. The software unit 4 is composed of a plurality of commands, and includes a graphic definition command 4a, a plate setting command 4b, a parts database registration command 4c,
Parts attachment command 4d, plate division command 4e, N
There are C data generation commands 4f and the like. In the software section 4 of FIG. 15, the “command” is omitted. The edited drawing database 5 stores graphic data 5a, plate setting data 5b, and plate processing data 5c. The display device 6 is a CRT display device, and its screen has a graphic display portion 6a, a command selection portion 6b, a message display area 6c, and a mouse cursor 6d. The input device 7 is a mouse 7a, a tablet 7b and a keyboard 7
The output device 8 comprises a floppy disk drive 8a and a plotter 8b.

Next, the operation will be described. In addition,
In the following description, a mold die is assumed as the die. <Database Registration> First, registration of each database in the external storage device 2 will be described. The registration of the parts database 2a is a database updating operation performed when a new part is needed. The component database 2a stores the mold bases registered up to now and the graphic data of the mold components such as pins and bushes. When a mounting hole is generated when the component is mounted on the mold base, each composite hole in the composite hole database 2b is associated with each part in the component database 2a. This composite hole is registered as a combination of simple holes for each plate. The simple hole figure database 2c stores the shape data of each simple hole. In the simple hole processing database 2d, processing data indicating how to process each simple hole is registered. This processing data includes processing order such as center → drill → prepared hole drill → tap, and processing conditions such as spindle speed and feed rate. These external storage devices 2
The operator can use the parts database registration command 4c to register data in each of the databases.

FIG. 16 shows the concept of each database in the external storage device 2. Parts database 2a
And as shown in the compound hole database 2b, as the parts, for example, ejector pin mounting holes are KEG, KDN, KC.
It is a combination of 3 simple holes, X, and KE 4 on the back.
The notation G indicates that a simple hole named KEG will be attached to the plate 4 from the back. The machining methods of the simple holes KDN, KEG, and KCX of the simple hole figure database 2c are registered in the simple hole machining database 2d. For example, the simple hole KCX is machined in the order of center → drill → counterbore → chamfer. Is registered. in this way,
Parts database 2a, compound hole database 2b, simple hole figure database 2c, and simple hole machining database 2
d is registered in association with each other. 17 to 20 show screens in which each part of the parts database 2a is being set. FIG. 17 is a screen in which parts are registered, FIG. 18 is a screen in which compound holes are registered, and FIG. 19 shows a screen in which a simple hole shape is registered, and FIG. 20 shows a screen in which a simple hole machining method is registered.

<Mold Drawing Creation> Next, the procedure for creating the drawing will be described with reference to the flowchart of FIG. First, in step S101, as a process of calling the mold base, the operator calls the mold base from the parts database 2a by the parts attachment command 4d. When the mouse 7a is operated and the mouse cursor 6d is aligned with the position of the component attachment command 4d of the command selection unit 6b and the button of the mouse 7a is pressed, the component attachment command 4d is activated. Keyboard name 7
Enter with c. When the mouse cursor 6d is moved to the mounting position of the mold base and the button is pressed, the mold base is quoted at that position. FIG. 22 shows a screen in which the mold base is called. The drawing data of this mold base has a laminated structure of each plate. Next, in step S102, the plate thickness, material, etc. are set by the plate setting command 4b as plate setting processing. When a command is selected, a setting table is displayed on the screen, so that the mouse cursor 6d is moved to the item to be set and a numerical value is input from the keyboard 7c. Finally,
Select / Exit / Menu to set plate command 4
b ends. FIG. 23 shows a screen for setting the table contents.

Next, in step S103, as a component mounting process, the operator selects a mounting component by the component mounting command 4d and mounts it on the mold base.
The operation here is the same as in step S101. Next, the process proceeds to step S104, and as the position definition processing of the component mounting hole, the mounting hole of the component is defined in the component database 2a, and the position of the mounting hole is defined. here,
The position of the mounting hole is defined by inputting the coordinates for setting the mounting hole from the keyboard 7c or specifying the position with the mouse 7a. In addition, when mounting one part at several places, the coordinate designation is repeated. FIG. 24 shows a screen in which one part and a mounting hole are defined. Since the component database is configured as described above, the mounting holes are defined for each of the plurality of plates. Next in step S10
Then, the process proceeds to step S5, in which a process for determining whether or not all parts have been completed is executed. If there are any parts to be installed, the process returns to step S103 and the same process is repeated. When the installation of all parts is completed, the process moves to the next step S106.

In step S106, as a completion process of the die drawing, the operator adds necessary data such as notes and dimensions by the figure defining command 4a to complete the die drawing. The figures created at this time are defined by designating which plate they belong to. Next, in step S107, as a die drawing output process, the completed die drawing is stored as a drawing file in the external storage device 2 or the floppy disk of the floppy disk drive 8a, or is output as a drawing by the plotter 8b. To do. Note that FIG. 25 shows a screen for displaying a completed drawing of the die drawing.

<Creation of Plate Drawing and Generation of NC Data> Next, the procedure of generation of each plate drawing and generation of NC data will be described with reference to step S108 and subsequent steps in FIG. In step S108, as the division processing of the n-th plate diagram, the operator divides the plate diagram one by one from the die drawing by the plate division command 4e. At this time, the operator need only specify which plate to divide. In the die drawing, since the graphic portion of the mold base is defined as the laminated structure of each plate, only the portion belonging to the designated plate remains. The drawing data of the part does not belong to any plate by itself and is deleted. The component mounting holes remain after being disassembled into simple holes in each plate. FIG. 26 shows a screen of one divided plate drawing. Next, the process proceeds to step S109, and plate plate completion processing is executed. In step S108, the divided plate drawing may be hidden under another plate in the mold drawing, and the line type that should be a solid line remains a broken line.
Therefore, it is necessary to change the line type, make other notes, write dimensions, and complete the drawing. This work is performed by the graphic definition command 4a. Then step S
In step 110, the completed plate diagram is output as the plate diagram output processing.

Next, in step S111, NC data generation processing for plate front processing is performed, and in step S112 NC data generation processing for plate back processing is executed. The operator uses the NC data generation command 4f to create NC data for drilling holes in the plate drawing. If the plate needs to be processed from both the front and back, NC twice
Generate data. When the NC data generation command 4f is executed, it is designated whether to generate front data or back data. Note that FIG. 27 shows a state of the screen when the NC data for plate surface processing is generated.
At this time, a simulation of the processing state is being performed on the screen. Similarly, FIG. 28 shows the appearance of the screen when the backside of the plate is processed. Next, the process proceeds to step S113, a process of determining whether or not all the plates have been completed is executed, and if there is another plate to be processed, step S108.
Then, the same processing is repeated, and when the NC data generation for the machining of all plates is completed, the work is terminated.

[0010]

By the way, as described above, the conventional mold design support apparatus can perform drawing creation and NC data generation for each plate which is a mold component, but other than the plate. , Molds such as cavities, cores, sliders (also called "nesting")
Was lacking consideration. These molds are themselves mold parts, and the mounting holes of other related parts must be machined, but it is extremely complicated to handle molds with a conventional mold design support device. there were.

Further, after the plate is divided, when the plate drawing is completed, the work of correcting the line type of the hole shape occurs, but it is necessary to consider one by one which circle of which hole should be a solid line or a broken line. There was a lot of work to do.

When the mold is divided into the movable side and the fixed side, and it is attempted to design in the state of the mold splitting, it is not clearly defined which is the front side or the back side of the plate, and the shape of the hole is not defined. When the work of correcting the line type occurred, it was necessary to consider one by one which circle of which hole should be corrected to a solid line or a broken line, and this work was very complicated.

Furthermore, there are several kinds of plate configurations which are the structures of the molds, and they differ depending on the mold to be designed.
In some cases, although the plate to be omitted appears in the mold structure, the specification cannot be omitted in the plate setting, so that an unnecessary component mounting hole was generated due to the nonexistent plate.

The registration of the component mounting holes in the component database is a method of attaching a simple hole to either the front side or the back side of one plate, and it is necessary to machine one hole from both the front side and the back side. The hole could not be registered. Therefore, it is very difficult to process such a hole.

In addition, the mounting holes of parts such as bushes and pins, which are used in combination when they are used and are used separately when they are used, must be registered as combined parts. However, there was a problem that the number of parts to be registered was increased and the effort was increased.

Therefore, the present invention has been made to solve the above-described problems, and makes it possible to handle molds such as cavities, cores and sliders in the same manner as other plates, thereby creating drawings and NC data. It is an object to provide a die design support device that can efficiently generate.

Another object of the present invention is to provide a mold design support device which can eliminate the work by having a function of changing the hole line type after the plate division. There is.

According to the present invention, when designing a mold with a mold splitting diagram, it is clear by setting whether each plate has a movable side or a fixed side as a table to clarify the line type of the hole. It is an object to provide a mold design support device that can eliminate the need for changing work.

Further, according to the present invention, it is necessary to input only the necessary plates according to the mold structure to be designed, and it is only necessary to set the plate not to be used in the mold structure so as not to use unnecessary mounting holes. The challenge is to provide a die design support device that does not occur.

According to the present invention, when registering a component mounting hole, it is possible to register holes to be machined from the front and back of one plate, or both, so that a die design support that can be handled in the same way as a hole machined from one side The challenge is to provide equipment.

In addition, according to the present invention, when two or more holes are defined at the same coordinate, the generation of NC data of a hole having a small diameter is omitted when the NC data is generated.
The object of the parts database is to provide a die design support device that can define a combination part by simply registering the part independently of the combination of parts.

[0024]

When registering composite holes for multiple plates or molds that are mounting holes for parts by combining multiple combinations of simple hole shapes for which data has been registered, processing from the front and back sides of a single plate or mold is possible. If necessary at the same time, the front and back sides can be registered at the same time.

According to a fifth aspect of the present invention, there is provided a die design support apparatus according to any one of the first to fourth aspects, further including mounting holes for mounting two or more parts at the same coordinate position.

EXAMPLES The present invention will be described below based on specific examples. 1, FIG. 2 and FIG. 3 are display screens to which the mold design support apparatus according to one embodiment of the present invention is applied, and display plate settings, mold settings and mold base drawings, respectively. Here, the description of each condition of the plate setting and mold setting display screens in FIGS. 1 and 2 will be given as needed. Since the basic configuration of the device of this embodiment is apparently the same as that of the above-mentioned conventional device, reference is made to FIG. 15 showing the overall configuration thereof, and detailed description thereof will be omitted. In addition, in FIG.
Corresponding to each plate No. or each mold No. in the plate setting of FIG. 2 or the mold setting of FIG. 2, for example, the fixed side mounting plate of the plate No. 1 is N1, the cavity 1 of the mold No. 21 is N21. To indicate which plate or mold each corresponds to.

Next, the operation of the mold design support apparatus according to the embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a flow chart showing a procedure for creating a die drawing used in the die design support apparatus according to the embodiment of the present invention. This operation procedure is basically the same as the flow chart shown in FIG. 18 of the related art, but a big difference is that in addition to the plate which is a component of the mold, the mold such as the cavity, the core, and the slider can be handled. That is. Note that in FIG. 4, the parts that perform the same processing as in FIG.
The same step number is given to simplify the description. Referring to FIG. 4, first, in step S101, the operator calls a component mounting command 4 as a mold base calling process.
The mold base is called from the parts database 2a by d. Next, step S for achieving the input condition setting means.
In step 102, as plate setting processing, the plate setting command 4b sets conditions such as thickness and material for each plate. As input items on the plate setting screen of FIG. 1, a setting area 11 for the plate No., a setting area 12 for the plate name corresponding to each plate No.,
A plate-state setting region 13, a plate-thickness setting region 14, a plate-spacing setting region 15 between the plates above each plate, and a plate-material setting region 16. Of these, the input items in the plate-state setting area 13 are not present in the conventional apparatus, and the contents will be described later. In this embodiment, 10 plates No. 1 to No. 11 (of which No. 2 is set not to be used) are stacked in the setting area 11 of the plate No. I have just done it. For example, the fixed template of the plate No. 3 has a thickness of 50 mm and is made of material S55C. In addition, the upper and lower order of the plate setting table indicates the order in which the plates are overlapped with each other.
It is shown that the fixed-side mounting plate of the plate No. 1 exists on the fixed-side template of the plate No. 3 and the stripper plate of the plate No. 4 exists below the fixed-side mounting plate.

Next, the process proceeds to step S114 for achieving the input condition setting means, and as the mold setting process, the plate setting command 4b sets input items such as the thickness and material of the mold as with the plate. . As the input item on the screen for setting the mold die of FIG. 2, the mold die No. setting area 1
7. Setting area 18 of mold name corresponding to each mold No., setting area 19 of mold status (details will be described later), and mold reference surface showing plate number which is reference surface of each mold. Setting area 20, setting area 21 of the mold front and back (whether the reference surface is the front or back of the plate), setting area 22 of the mold top thickness (the thickness of the mold from the reference surface to the top) , A die bottom thickness (die thickness from the reference surface to the bottom) setting area 23 and a die material setting area 24. Therefore, in the conventional device,
There is no procedure to set molds for cavities, cores, sliders, etc. that require machining of mounting holes for other parts even though they are parts to be mounted on the plate. What I needed to do was
Similar to the plate setting, it can be set as a series of operations. For example, the cavity 1 of the mold No. 21 uses the back surface (3-back) of the stationary mold plate of the plate No. 3 as a reference surface, and has a thickness of 40 mm above the reference surface and a material NAK55.
Is shown. Also, the core 1 of mold No. 23
Shows that the surface (5-table) of the movable mold plate of the plate No. 5 is used as a reference surface, the thickness is 50 mm above the reference surface, the thickness is 20 mm below, and the material is NAK55.
FIG. 3 shows the positional relationship between each plate and each mold. By registering in this way, the software can correctly determine the positional relationship between the plate and the mold. However, plate No.
Input error check is performed so that the plate No. and die No. cannot be overlapped like each other. In this way, both the plate setting and the mold setting are performed by the plate setting command 4b, and the edited drawing database 5
Stored in the plate setting data 5b.

Next, step S for achieving the component mounting means.
The processing of 103 and step S104 is executed. In step S103, as a component mounting process, the operator selects a mounting component by the component mounting command 4d and mounts it on the mold base. The operation here is step S10.
The same as 1. Next, the process proceeds to step S104, and the component database 2a is used as the position defining process of the component mounting hole.
The mounting holes of the parts are defined in, and the positions of the mounting holes are defined. Here, the position of the mounting hole is defined by inputting the coordinates for setting the mounting hole from the keyboard 7c or specifying the position with the mouse 7a. In addition, when mounting one part at several places, the coordinate designation is repeated.
Since the parts database has the above-described configuration, the mounting holes are defined for a plurality of plates or molds, respectively. At this time, if a mounting hole is generated in the plate or the mold, it is registered in the plate processing data 5c of the edited drawing database 5 together. Next step S1
In step 05, a process for determining whether or not all parts have been completed is executed. If there are any parts to be attached, the process returns to step S103 and the same process is repeated. When the installation of all parts is complete, the process moves to step S106.

Step S106 for achieving graphic defining means
Then, as the completion process of the die drawing, the operator adds necessary data such as notes and dimensions by the figure definition command 4a to complete the die drawing. The figures created at this time are defined by designating which plate or die they belong to. Next, in step S107, the completed die drawing is stored as a drawing file in the external storage device 2 or the floppy disk of the floppy disk drive 8a as the die drawing output process.
The plotter 8b outputs it as a drawing.

Then, the process proceeds to step S115 for achieving the disassembled drawing creating means, and the operator performs the plate division command 4e as the division processing of the nth plate drawing / mold drawing.
According to, the plate drawing or the mold drawing is divided one by one from the mold drawing. At this time, the operator need only specify which plate or die to divide. In the die drawing, the graphic portion of the mold base is defined as a laminated structure of each plate or each die, so that only the portion belonging to the designated plate or die remains. The drawing data of the part is deleted because it does not belong to any plate or mold by itself. The component mounting holes remain after being disassembled into the simple holes of each plate or die. Next, the process proceeds to step S116 of achieving the figure defining means, and the plate diagram / mold diagram completion processing is executed. Step S1
The plate drawing or mold drawing divided by 15 may be hidden under another plate or mold in the mold drawing, and the line type that should be a solid line remains a broken line.
Therefore, it is necessary to change the line type, make other notes, write dimensions, and complete the drawing. This work is performed by the graphic definition command 4a. Then step S
In step 117, the completed plate diagram or mold diagram is output as the plate diagram / mold diagram output process.

Next, the processing of steps S118 and S119 for achieving the NC data generating means is executed.
In step S118, the NC data generation process of the plate / die metal surface processing is performed, and in step S119, the plate / die metal back processing NC data generation process is executed. Operator is N
Using the C data generation command 4f, NC data for making a hole in the plate diagram or the die diagram is created. If the plate or die needs to be machined from both the front and back, then generate NC data twice. When the NC data generation command 4f is executed, it is designated whether to generate front data or back data. Then step S
In step 120, a determination process is performed to determine whether all plates / molds have been completed. If there are other plates or molds to be processed, the process returns to step S115 and the same process is repeated to repeat all plates or molds. When the NC data generation for gold processing is completed, the operation according to this flowchart is ended. In the middle of the above procedure, the operator uses the parts database registration command 4c for a newly generated figure or the like on the display screen to register it in the parts database 2a of the external storage device 2 as necessary. You can In addition, step S115 to step S1 of creating NC data for plate / die processing described above.
20 is the conventional step S108 to step S of FIG.
This is a series of processes in which the process executed on the plate diagram in 113 is expanded to the mold diagram to be the target of NC data creation.

As described above, the die design support apparatus according to the present embodiment specifies which of the plates or die figures that are stacked to form a die and the figure to be created belongs to and is required. A figure defining means achieved by using a figure defining command 4a to which data is added and expressed on a die drawing, and a plate setting command 4 for setting a predetermined condition including mutual data in the plate or the die.
b, an input condition setting means achieved by using b, a part database registration command achieved by using a part database registration command 4c for registering graphic data of a part to be attached to the mold and data regarding machining of a mounting hole, and A component mounting means achieved by using a component mounting command 4d for designating the mounting position of the component with respect to the die drawing, and the completed die drawing is disassembled for each plate or each die and the plate drawing or It is possible to provide an embodiment including an exploded drawing creating means that is achieved by using a plate division command 4e that creates a die drawing.

Therefore, the graphic definition means 4a, the input condition setting means a plate setting command 4b, the part database registration means a part database registration command 4c, the part mounting means a part mounting command 4d, and the exploded drawing creating means a plate. Drawings are created by the same operation procedure for the mold as well as the plate that constitutes the mold by using each command of the division command 4e.

Therefore, in designing the mold, the drawings of the plate and the mold can be efficiently created.

Here, the plate setting command 4b which achieves the input condition setting means of the apparatus of this embodiment simultaneously solves the following problems. In the conventional device, it was necessary to change the line type of the hole after the plate was divided. In the mold assembly drawing, most of the plates or molds have overlapping plates or molds, and in the plan view, the hidden holes are indicated by broken lines. However, after the plate is divided, there is no plate or metal mold which is overlaid on the plate, so that the hole represented by the broken line needs to be corrected to the solid line. FIG. 5 is an explanatory view showing a line type change in plate division of the movable side mold plate N5 which is the plate No. 5, FIG. 5 (a) is a drawing immediately after plate division, and FIG. 5 (b).
Shows the drawing after changing the plate line type. When dividing the plate, as shown in FIG. 5, it is not necessary to simply modify the broken line holes to solid lines. Instead, the holes visible when viewed from the front side of the plate or the mold are set to solid lines. The holes on the back side of the mold must remain dashed. The holes sometimes consist of many circles, which can be difficult with complex plates or molds.

Therefore, in the apparatus of this embodiment, a plate-state setting area 13 and a die-state setting area 19 are provided as conditions for the screen for plate setting and die setting. In this input item, "None", "Normal", "Hidden",
It is possible to set five states consisting of "reverse" and "reverse hidden". Of these, "none" indicates that the plate or die is not used. "Normal" indicates that it is at the top. "Hidden" indicates that it is below the other plate. The “reverse” and “reverse hiding” will be described later. When the operator sets the input items, the line types of the component mounting holes generated in each plate or die are then inherited. When this setting is changed, the line type of the mounting hole that has already occurred is automatically changed. This solves the above problem. It is possible to easily switch the line type of the hole in the state of the assembly drawing and the line type of the hole when the plate is divided or the mold is divided. Immediately after calling the mold base, this setting is automatically performed.

As described above, the input condition setting means achieved by using the plate setting command 4b of the die design support apparatus of this embodiment is the die drawing as the mutual data for each plate or die. It is possible to set whether it is placed on the top or hidden under another plate or mold, and is defined in the plate or mold corresponding to the change of setting. The present invention can be an embodiment in which the display state represented by the solid line or the broken line of each existing hole is automatically changed, and a newly defined hole is created according to the setting.

Therefore, the input condition setting means can set whether each plate or mold is placed at the top of the mold drawing or hidden behind it. Corresponding to the change of the setting, the plate or mold can be set. The display state of each hole defined and existing in the mold is automatically changed, and the newly defined hole is created according to the settings.

Therefore, the vertical relationship of each plate or each mold on the mold drawing becomes clear, and the operation of making the display state of each hole defined and present on each plate or each mold a solid line or a broken line is possible. Be automated.

Further, the plate setting command 4b which achieves the input condition setting means of the apparatus of this embodiment simultaneously solves the following problems. In the conventional apparatus, when designing a die drawing, it was difficult to understand when designing in a state of a mold split drawing. This point will be described with reference to the mold splitting diagram of FIG. 6A is a plan view of the mold cutting / moving side, FIG. 6B is a front view of the mold cutting / moving side, and FIG. 6C is a plan view of the mold cutting / fixed side. FIG. 6 (d) is a front view of the mold splitting / fixed side. When writing a die-cutting diagram such as that shown in FIG. 6, it was difficult to determine which was the front side or the back side of the plate because the fixed side was turned over on the die-cutting surface. If you turned the inside out, you had to change the hole linetype. With a two-plate mold, you just split it into two,
It was more complicated when writing with more division planes, such as 3 plates. The mold splitting drawing is a drawing drawing method that is often performed at the time of designing a mold, and its inconvenience has a big problem, and some solution has been demanded.

Therefore, in the apparatus of the present embodiment, it is possible to freely write this mold cutting diagram by defining that "the fixed side is always the table" and setting the items in the above state for each plate or mold. I made it possible. That is, "normal position" and "hidden" indicate that the fixed side is on top (front side up), and "reverse position" and "reverse hiding" are on the movable side (back side up). Indicates that it is placed). The difference between "reverse" and "reverse hidden" is the same as the difference between "normal" and "hidden". When the operator sets this condition, it is inherited by the setting of the line type of the component mounting hole generated in each plate or die after that. Also, if this setting is changed, the line type of the mounting hole that has already occurred is automatically changed. This solves the above problem.

In the case of designing with a mold splitting diagram, for example, FIG.
If set as above, the subsequent processing can be handled in the same manner as in the case where the pattern layout diagram is not used. In the case of FIG. 7, the plate No. which is the fixed side.
Plate No. 3 is reversed from 1 and plate No. 3 is at the top, so "reverse", plate No. 1 and plate N
o.2 is set as "reverse hiding". On the movable side, the plate No.
Since 5 is the top, set "normal" and the rest as "hidden". When the hole is defined after this setting, whether to draw the plan view of the hole with a solid line or a broken line is automatically determined according to the setting from the positional relationship of each plate.

As described above, the input condition setting means achieved by using the plate setting command 4b of the die design support apparatus of this embodiment is the die drawing as the mutual data for each plate or die. It is possible to set whether it is placed with the fixed side up or the movable side up, and each existing defined in the plate or the mold corresponding to the change of the setting. This is an example in which the display state represented by a solid line or a broken line of a hole is automatically changed, and a newly defined hole is created according to the setting.

Therefore, by the input condition setting means, the direction of the fixed side or the movable side can be clarified and set for each plate or mold, and the plate or mold can be defined according to the change of this setting. The display state of each existing hole is automatically changed, and a newly defined hole is created according to the settings.

Therefore, when creating a mold splitting diagram, the upper and lower relationships of the plates or the molds are clarified only by designating the direction of the fixed side or the movable side on the mold drawings, and they are defined on each plate or each mold. The operation of making the display state of each existing hole into a solid line or a broken line is automated.

Further, the plate setting command 4b which achieves the input condition setting means of the apparatus of this embodiment simultaneously solves the following problems. FIG. 8 shows plate configurations of various molds. Here, T is a fixed side mounting plate, A
Is a fixed-side template, S is a stripper plate, B is a movable-side template, U is a receiving plate, C is a spacer block, E is an ejector plate, F is an ejector plate, and L is a movable-side mounting plate. . In FIG. 8A, the stripper plate S is not provided, but the receiving plate U is provided. In FIG. 8B, there are both the stripper plate S and the receiving plate U. In FIG. 8C, neither the stripper plate S nor the receiving plate U is provided. This difference in structure occurs in order to select the optimum plate configuration depending on the shape and size of the molded product.

By the way, the operator uses the plate No. or mold No. instead of the plate name or mold name, for example, the movable mold plate is plate No. 5 and the ejector plate is plate No. 7. I want to determine the type of plate or mold by associating with it. In other words, due to the difference in plate structure, when the movable side mold plate is the plate No. 3 or the plate No. 4 in some cases, it is difficult to understand when the plate No. is designated. Therefore, in the conventional apparatus, in order to avoid the above-mentioned problem, for example, in the plate setting of FIG. 23, the stripper plate of the plate No. 4 has a thickness of 0, and the plate is not used.

In such a method, since the stripper plate is formally present, when mounting the parts,
Holes will also be created in stripper plates that do not actually exist. That is, even a circle of unnecessary holes is displayed in the created plan view or the like, which is different from the desired drawing.

Therefore, in the apparatus of this embodiment, in the plate setting command 4b which achieves the input condition setting means, as in the runner stripper plate of the plate No. 2 of FIG. It is possible to set "None" and it is omitted so that no component mounting hole is generated for the plate that is set to "None" and not used. As a result, unnecessary holes are no longer generated and correct plan views can be obtained.

As described above, the input condition setting means achieved by using the plate setting command 4b of the mold design support apparatus of the present embodiment should not be used for the plate or mold which is omitted in the mold structure to be designed. And the component mounting means achieved by using the component mounting command 4d is such that the component mounting hole cannot be defined for the plate or the die set not to be used. be able to.

Therefore, the input condition setting means can set the use state of the plate or the die omitted in the designing die structure, and the component attaching means attaches the component attaching hole to the plate or the die of the omitted setting. Can be undefined.

Therefore, in setting the plate or the mold, only the plate or the mold suitable for the mold structure to be designed needs to be input, and unnecessary plate mounting holes are not generated for the plate or the mold not used.

Furthermore, the plate setting command 4b which achieves the input condition setting means of the apparatus of this embodiment simultaneously solves the following problems. As the material of the plate or the die forming the die, not only ordinary carbon steel but also pre-hardened steel or the like is used. Therefore, when processing the mounting hole of the component, it is necessary to perform the processing under the processing conditions in consideration of the material of the plate or the die. However, only one standard type can be registered in the machining conditions of the simple hole machining database 2d of the conventional apparatus, and the machining conditions are set for the molds that use different materials for each plate or mold. Couldn't be optimal.

Therefore, in the plate setting command 4b of the apparatus of this embodiment, the plate material setting area 16 is set as the condition of the screen for performing the plate setting of FIG. 1 and the mold setting of FIG.
And a setting area 24 for the mold material. The conditions in this case are set so that S55C is used for the plate and NAK55 is used for the die. The operator selects the material to be used this time from the plate or die material registered in advance in the system. The component attachment command 4d in the apparatus of this embodiment changes the machining conditions registered in the simple hole machining database 2d by using the data of the plate or die material when the component is mounted and a mounting hole is generated. By doing so, it is possible to absorb changes caused by the material. This system has rules for each material regarding how to change the processing conditions depending on the material. For example, a certain material can be processed at a speed α times faster than standard carbon steel, so the rule is to multiply the coefficient α by the conditions.

As described above, the input condition setting means achieved by using the plate setting command 4b of the die design support apparatus of this embodiment can set the material of the plate and the die, and the component attaching means. Can be an embodiment in which the processing conditions of the mounting hole are changed according to the set material of the plate or the mold.

Therefore, the material for the plate or die can be set by the input condition setting means, and the processing conditions for the mounting hole can be changed by the component attaching means according to the material for the plate or die.

Therefore, the material of the plate or the die can be set, and the processing conditions of the mounting hole can be changed from the standard conditions according to the material of the plate or the die to adapt to the change of the material of the plate or the die. .

Next, a supplementary description will be given of how the above contents are internally processed in the apparatus of this embodiment. FIG. 9 is a flowchart showing an internal process of setting a part / hole. Based on the procedure of the flowchart of FIG. 9, first, in step S201, the data of the component name and the mounting position are input. Next, in step S202, it is searched whether the component name is registered in the component database 2a. Next, the process proceeds to step S203, and if the component is registered, the process proceeds to next step S204, and if not, step S201.
Return to and ask the operator to re-enter. Step S20
In 4, the part data (graphic data) is added to the data of the drawing currently being edited. Up to this point, the graphic of the part is displayed on the screen. Next, in step S205, it is searched whether the compound hole associated with the part is registered in the compound hole database 2b. Next, the process proceeds to step S206, and if the compound hole is not associated with the part, this flowchart is ended, and if the compound hole is associated, the process proceeds to step S207. In order to attach holes to each plate or each mold, in step S207, n
The simple hole graphic database 2c is searched for a simple hole corresponding to the th plate / mold. Next, the process proceeds to step S208. If there is no simple hole, the process proceeds to step S215 described below, and if there is a simple hole, the process proceeds to step S209.
In step S209, if the state of the n-th plate / mold is “none” and the setting is not to be used, step S will be described later.
If it is set to be used when the state of the n-th plate / mold is other than "none", the process proceeds to step S210.

In step S210, the mth stage of the hole figure is read from the simple hole figure database 2c. In the next step S211 to step S213, for each step forming the simple hole, check whether the front or back side, the state of the plate or the mold, and whether the simple hole is a hole from the front side or the back side. , Depending on the state of the nth plate / mold, the line type of the hole figure to be created, whether to write with a solid line or a broken line, is determined and added to the drawing currently being edited. And step S
In step S214, the same process is repeated for each stage until the processes in steps S210 to S214 are completed. When the process for all stages is completed in step S214, the process proceeds to step S215. In step S215,
The same process is repeated until the processes of steps S207 to S215 are completed for each plate or each mold, and when the processes for all plates / molds are completed in step S215, the figures of parts and holes are displayed on the screen. This flowchart ends.

FIG. 10 is a flow chart showing the internal processing for changing the plate / mold state. Based on the procedure of the flowchart of FIG. 10, first, in step S301, the plate or mold state is input as a change of the plate / mold state. Next, in step S302, the condition state for the nth plate / mold is compared with the previous state. Next, in step S303, if the state compared in step S302 is the same as the previous one, the process proceeds to step S309 described below, and if the state is different from the previous one, the process proceeds to step S304 and the n-th It is determined whether or not the setting is to be used when the plate / mold condition is other than "none". When the state of the n-th plate / die is not used because the state of the n-th plate / die is not set in step S304, the process proceeds to step S309, and when the n-th plate / die is used, the process proceeds to step S305. . In step S305, one graphic element is read from the data of the current edited drawing, and the process proceeds to step S306. If the graphic element belongs to the nth plate / mold, the process proceeds to step S307. Step S307
Then, the line type is changed depending on the state of the nth plate / mold. When the graphic element read in the above step S306 does not belong to the nth plate / mold,
Step S307 is skipped. Next in step S30

The same process is repeated until the process of step S309 is completed, and when the process for all plates / molds is completed in step S309, this flowchart is completed.

FIG. 11 is a flow chart showing the internal processing of plate / die split storage. Based on the procedure of the flowchart of FIG. 11, first, in step S401, the plate No. or mold No. to be divided is input as the plate / mold die divided storage. Next, the process proceeds to step S402, and it is determined whether or not the setting of the n-th plate / mold is other than "none". If the state of the n-th plate / die is not used because the state of the n-th plate / die is not set in step S402, the process proceeds to step S409, which will be described later. If the n-th plate / die is used, the process proceeds to step S403. . In step S403, a file for saving the drawing is opened (prepared). Next, the process proceeds to step 404, one graphic element is read from the data of the current edited drawing, the process proceeds to step S405, and if the graphic element belongs to the designated plate / mold, the process proceeds to step S406. In step S406, the line type of the graphic element is changed and saved in the file. At this time, when the state of the plate or mold is "hidden",
In the drawing after dividing the plate or die, it may change from a broken line to a solid line. The graphic element read in step S405 is the designated plate /
If it does not belong to the mold, step S406 is skipped. Next, the process proceeds to step S407, and the same process is repeated for all graphic elements until the processes of steps S404 to S407 are completed, and step S4 is performed.

When the dividing process for the mold is finished, this flowchart is finished.

Next, the improvement regarding the registration of the parts database 2a will be described. Consider a case where holes required to be machined are simultaneously registered from the front side and the back side with respect to one plate as shown in FIG. When making spot facing on both the front and back sides, it is possible to process from the front side only with a back spot facing tool, but if the number is large, it is more efficient to turn the plate over. Since this type of hole could not be registered in the conventional device, the hole was processed by replacing it with another hole shape.

Therefore, the apparatus according to the present embodiment uses the parts database registration command 4 for achieving the parts database registration means.
Made improvements to c. First, the hole in FIG. 12 (a) is machined from the front and the hole KFZ in FIG. 12 (b) is machined from the back.
Disassemble into the hole KWR in (c). Each of the figures is registered in the simple hole figure database 2c, and the machining method is registered in the simple hole machining database 2d. Next, using the setting screen of FIG. 12D, the hole KFZ and the hole KWR are combined and registered in the composite hole database 2b. It should be noted that in FIG.
Reference numeral 1 is a registration item of holes to be machined from the front side, and 52 is a registration item of holes to be machined from the back side. FIG. 1 showing a registration screen of a conventional device
In FIG. 8, only one of the holes on the front side or the back side can be registered in one plate, whereas in FIG. 12D showing the registration screen of the apparatus of this embodiment, both of them can be registered at the same time. Further, since the registration items 51 and 52 may be left blank if there is no hole in the processing direction, all the items that can be registered as shown in FIG. 18 can also be registered in FIG. 12 (d).

Regarding the operation after the registration, in the final NC data generation, the hole KFZ is processed when the surface is processed, and the hole KWR is processed when the back is processed.
This kind of hole can be handled exactly like the conventional operation. Note that the hole KWR is registered in the simple hole machining database 2d so that only the spot facing is performed without machining the center hole and the prepared hole on the premise that the front machining is performed before the back machining.

As described above, the part database registration means achieved by using the part database registration command 4c of the mold design support apparatus of the present embodiment stores the data regarding the shape and processing of the hole for one plate or the mold. When registering composite holes for multiple plates or molds that are mounting holes for parts by combining multiple registered simple hole shapes, it is necessary to process one plate or mold from the front and back sides at the same time. In such a case, it is possible to adopt an embodiment in which the front and back sides can be registered simultaneously.

Therefore, when the parts database registering means registers a plurality of simple hole shapes of one plate or mold to register a composite hole for a plurality of plates or molds which are mounting holes for parts, When simultaneous processing from the front and back of a single plate or mold is required, it is registered at the same time.

Therefore, even when it is necessary to simultaneously process one plate or die from the front and back, registration can be performed in the same manner as in the case of processing from either the front or back.

Finally, the improvement regarding the combination of parts and the definition of overlapping holes will be described. In the conventional device, a method of defining one type of mounting hole for one type of component is adopted. Therefore, for example, the pin shown in FIG.
The component mounting holes (pin mounting holes and bush mounting holes) for the bush shown in FIG. 13B are defined separately. However, when these are used in combination,
As shown in (c), a plate in which a plurality of mounting holes overlap at the same coordinates occurs. That is, in the plate A, drilling is specified for two mounting holes, a pin mounting hole and a bush mounting hole, and pin mounting holes smaller than the bush mounting hole are also targeted for drilling. If this is left as it is, the hole for the pin mounting hole that does not require hole processing is also processed, so it is necessary to delete the unnecessary hole before generating the NC data. However, as the number of parts and the number of combinations increase, this work becomes very difficult.

In order to solve this problem, a method of registering a combination of a pin and a bush as one component from the beginning can be considered. However, usually, several types of pins and several types of bushes can be combined, and the number of combined parts is the number obtained by multiplying them. In other words, when several types of parts are combined, it is necessary to combine an extremely large number of parts, and the work of registering the parts database is complicated, which is not the best.

Therefore, in the apparatus of this embodiment, the above problem is solved by improving the NC data generation command 4f that achieves the NC data generation means. In the parts database registration command 4c, when two or more holes are defined at the same coordinates, the respective hole diameters are compared, only the hole with the largest diameter is registered, and the remaining holes are ignored. Internal processing has been added. For example, as shown in FIG. 13C, the pin mounting hole is φ12 and the bush mounting hole is φ.
When it is 16, the drilling of the φ12 pin mounting hole is ignored. This process allows the operator to install the parts without having to worry about overlapping holes. Further, registration in the parts database 2a may be performed for each part, and it is not necessary to be aware of the combination.

FIG. 14 is a flow chart showing the internal processing of NC data generation. Based on the procedure of the flowchart of FIG. 14, first, in step S501, the operator inputs the plate No./mold No. for which NC data is generated. Next, in step S502, the plate /
Read out the mold material settings. Next, in step S503, one hole is selected from the drawing currently being edited. Next, in step S504, it is determined whether the selected hole is a plate No./mold No. hole for which NC data is to be generated. If it is determined in step S504 that this hole is not the hole of the plate for which NC data is generated, the process proceeds to step S510 described below, and if this hole is the hole of the plate for which NC data is generated, the process proceeds to step S505.
In step S505, it is checked whether this hole is included in another hole. In step S506, when this hole is included in another hole, step S51 described later is performed.
When it is 0 and the hole is not included in other holes and needs to be machined, the process proceeds to step S507 to read data for machining the hole from the simple hole machining database 2d. . Next, the process proceeds to step S508, and the processing conditions at this time are corrected by the material of the plate / die. Next, the processing proceeds to step S509, and the processing conditions of the previous hole are connected and temporarily stored. Then, the process proceeds to step S510 and step S50 is performed for all holes.
The same processing is repeated until the processing of 3 to step S510 is completed, and when the processing for all holes is completed in step S510, the process proceeds to step S511. Step S511
Then, in order to determine the machining order, the machining conditions temporarily stored by being connected after the machining conditions of the previous hole in step S509 are sorted. By this process, the process of drilling the prepared hole is collected in the first half of the machining, and the process of using the same tool is performed in parallel (collectively) to reduce the tool exchange.
Next, in step S512, an NC data file is opened (prepared), and then in step S513, the n-th plate /
Generate NC data of mold. Next, the processing proceeds to step S514, and the same processing is repeated until the processing of steps S513 to S514 is completed for all holes,
When the processing for all holes is completed in step S514, the process proceeds to step S515. In step S515, NC
The data file is closed (closed), and this flowchart ends.

As described above, NC achieved by using the NC data generation command 4f of the die design support apparatus of this embodiment.
The data generating means defines, when two or more mounting holes for mounting two or more parts are defined at the same coordinate position,
An example in which the largest hole diameter of the mounting holes is selected and NC data for hole machining is generated can be used.

Therefore, when two or more mounting holes are defined at the same coordinate position by the NC data generating means, the largest hole diameter of the mounting holes is selected and NC data for hole processing is generated. To be done.

Therefore, even when two or more parts are mounted at the same coordinate position and the mounting holes overlap, it is possible to obtain the NC data of the hole processing without waste.

[0086]

As described above, according to the die design support apparatus of the first aspect, whichever of the plate or the die forming the die by laminating a plurality of figures created by the figure defining means is arranged. It is designated on the mold, and the necessary data is added and the data is expressed on the die drawing. The input condition setting means sets a predetermined condition including mutual data on the plate or die. The parts database registration means registers the graphic data of the parts to be attached to the mold and the data on the processing of the attachment holes as required.
